Quality

ATTRIBUTE ACCURACY REPORT: A modified Eastern Otter trawl with a 17m horizontal opening was used. Tows were 30 min in duration at an average speed of 6.5 km h-1. Mesh size unknown. The inherent problem of trawls is to know exactly when the net reached and left the seafloor, because abundance and biomass calculations are based on the trawled area. The exact accuracy is unknown. LOGICAL CONSISTENCY REPORT: The same procedures were used at all sites and for all species; findings should be consistent. COMPLETENESS REPORT: Mesh size unknown. The data were taken from 70 stations with confirmed presence and absence reported from those stations. HORIZONTAL POSITIONAL ACCURACY REPORT: According to navigation system of NOAA ship Miller Freeman in 1976 VERTICAL POSITIONAL ACCURACY REPORT: According to navigation system of NOAA ship Miller Freeman in 1976 PROCESS DESCRIPTION: Catches were sorted on shipboard, given tentative identifications, enumerated, weighed, and fixed in 10% buffered formalin. Organisms mainly comprised epifauna, although some infauna was collected. Epifauna that could not be quantified and infauna were included in the taxa count, but not included in abundance, biomass calculations and multivariate analysis. Abundance and biomass were converted to individuals km-2 and kg km-2, respectively. General comments on distribution of epifauna were not collected quantitatively and some infaunal taxa are included in the results. PROCESS DATE: at sea When not provided by taxonomist, taxonomic information was completed using ITIS.
